The Standing Orders of the Philadelphia convention were modified on May 29, 1787 (what would have been their first day on the job) to drop the veil of secrecy over the work of the convention. Considered as a maneuver of preëemption against opponents of reform (outcome expected, given Congress’ resolution of February 21, 1787) the logic of secrecy exposes the possibility that it was a delaying device, staying the hand of reform supporters to launch their efforts until ‘signalled’ via publication of the final constitutional text.
